     conditions found to exist upon any such highway or part thereof
     and establish a reasonable and safe maximum limit. The maximum
     speed limit may be made effective at all times or at times
     indicated and may vary for different weather conditions and

     except on highways listed in section 3362(a)(1.1) (relating to
     maximum speed limits), where the maximum speed for all vehicles
     shall not be greater than 65 miles per hour.
